tangent of 3x^3-3x

tangent of

3 x^{3} - 3 x

y = (9 a_{0}^{2} - 3) x - 6 a_{0}^{3}

Solution steps

Compute the tangent line to the general point

x = a_{0}

Find the tangent point:

(a_{0}, 3 a_{0}^{3} - 3 a_{0})

Find the slope of

y = 3 x^{3} - 3 x : \frac{d y}{d x} = 9 x^{2} - 3

Compute the slope of

y = 3 x^{3} - 3 x

x = a_{0} : m = 9 a_{0}^{2} - 3

Find the line with slope m=

9 a_{0}^{2} - 3

and passing through

(a_{0}, 3 a_{0}^{3} - 3 a_{0}) : y = (9 a_{0}^{2} - 3) x - 6 a_{0}^{3}

y = (9 a_{0}^{2} - 3) x - 6 a_{0}^{3}

\frac{\partial}{\partial y} (\frac{4 ln ( y + 2 )}{x e ^{x}})

\int 7 x d x

\frac{4}{( x ^{2} - 1 ) ^{4}}

\frac{6}{5 x + 2}, at a = - 1

y^{^{'}} + 6 y = 60, y (1) = 90
